Thai and Lao borrowed from Khmer! Publication by UCLA

Most Thai and Laotian ppl would not admit that their culture and language were actually developed from Khmer's ...

Here are some quotes from K-I media and a publication by UCLA:

What a shame!

Taken this into account, Thai King Mongkut (reigned 1851-1868) have ordered our Angkor Wat to be disassembled stone by stone and moved to Bangkok. When the task was so massive and impossible to do it. He ordered the smaller temple Prasat Ta Prohm to be disasembled instead.

[Thai] HISTORY
The Thai, who originated in China, migrated into the Indochina peninsula before the current era. Initially dominated by the Mon and then later, beginning in the tenth century, by the Khmer,

the Thai gained their own independence in the mid-thirteenth century. Shortly thereafter, the first script--known as the Sukhotai and distinct from that used by the Khmer--was developed for Thai.

The script now in use is a more or less modified variant of this and other intervening scripts used during the reign of other monarchs.

ORTHOGRAPHY
Thai uses a script that is basically alphabetic in nature with some elements of a syllabic system. In origin it derives from an Indic script which was adapted first by the Khmer and then the Thai.

There is a fairly good approximation between the scriptand pronunciation.

LINGUISTIC SKETCH
Thai has borrowed heavily from Mon and Khmer.

[Khmer]HISTORY
The history of the language is distinguished into several periods: Old Khmer (the seventh to eighth century), Angkor period (the ninth to fifteenth century), Middle Khmer (the sixteenth to eighteenth century), and Modern Khmer. The language is attested from the earliest periods by numerous inscriptions, and then during the Middle Khmer period by extensive writings on palm leaf manuscripts, including the Khmer version of the Ramayana, a well-known Hindu epic about Rama.

During the Angkor period, Khmer influenced the surrounding languages, especially the unrelated languages of Lao and Thai, and they borrowed heavily from Khmer.
